SWINGING WINDOW.

Application filed January 23, 1923. Serial No. 614,384.

To all LU/0177, it may concern:

Be it known that I, HENRY T. ATKINSON, a citizen of the United States, residing at Oakland, county of Alameda, and State of California, have invented new and useful Improvements in Swinging lVindows, of which the following is a specification;

This invention relates to swinging windows.

In my Patent'No. 1,431,619, issued tober th. 1922, I show a plurality of swinging sashes having trunnions slidably mounted'in guides on the frame. Each sash is pivotally mounted on a pair of swinging links connected with the frame and a traveling bar or link connects the sashes together, so that they operate in unison.

The present invention has for its object to provide mechanism which will permit any one of the sashes to be positioned difierently from the others, the preferred method of doing this being by means of a clutch or releasable connection between the sash and the traveling bar.

One fbrm which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which Fig. 1 shows a perspective View of a wmdow embodying my invention with one of the jambs moved out of normal position.-

Fig.2 shows a horizontal sectional view taken on the line 22 of Fig. 1. v

Fig. 3 shows a vertical sectional view through one side of the frame.

Fig. 4 shows a modification of the device illustrated in Fig. 3.

The window includes a frame 10 and a plurality of swinging sashes 11, each having a pair of trunnions 12 sildably fitted in grooves 13 formed in the frame. A pair of fulcrum links let is pivotally connected intermediate the ends of each sash and to the sides of the frame. The trunnions of adjacent sashes are connected together by a traveling bar 15 which slides up and down in a groove 16 formed in a stop or weather strip 17.

Therefore, when one window is moved the others move in unison therewith, and, in order'to permit one window to occupy a different position from the others, I provide a clutch or releasable connection between the said traveling bars and the trunnions. Such a connection includes a pin 18 011 each trunnion extending loosely into an opening in the respective bar 15. The groove which receives the bar is enlarged adjacent the connection 18 and slidably received on the bar is a clip 19 which has a stem 20 extending through an opening in the stop or weather strip 17 As shown in Fig. 2 the stem has a lever 21 to engage an escutcheon plate 22 on the stop and exert an outward pull on the traveling bar when thelever is manipulated. In place of the lever 21 the stem may be provided with a button or nut 24 to be engaged by the hand forpulling the bar outwardly,

as shown in Fig. 4. The bar is thus pulled outwardly far enough to disconnect it from the pin 18 so that one sash can be operated independently of the other.

In the operation of the present mechanism it is possible by means of these clutches to bring about any combination of openings for the three sashes. For instance, when all three sashesare opened, the two upper ones may be left open while the bottom oneisclosed by manipulation of the levers 21, or

the bottom sash may be opened and the two upper ones closed. In fact, any desired -relative arrangement of the sashes may be obtained by the present clutch mechanism.

In some instances the trunnion pin on the left-hand side of the middle sash may be omitted and the lower and middle sashes may be connected together on their righthand side, whereas the top and bottom sashes will be connected together on the left-hand side. Thereby the top sash may be left open and the two bottom sashes closed.

Another advantage of the present clutch mechanism is that it may be used as a brake to hold the windows open against wind. This is done by raising the lever to disconnect the traveling bar from the pins on the trunnions, whereupon the traveling bar is friction-ally held against movement by engagement with the window stop.

It will be understood that the present clutch mechanism may be used on two or any other number of sashes.

Various changes in the construction and arrangement of the several parts herein shown and described may be employed without departing from the spirit of my invention as disclosed in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a window structure, the combination with a frame and a plurality of sashes pivotally and slidably mounted therein of a traveling bar arranged beneath a window stop and connecting said sashes together and means extending through said stop and operable from the exterior thereof to disconnect the bar from one of said sashes.

2. In a window structure, the combination with a frame, a plurality of sashes pivotally and slidably mounted therein, a window stop formed with a groove on its inner face, a traveling bar vertically movable in said groove, a clip through which the bar is slidable, said bar being detachably connected with one of the sashes and means on said clip extending through the stop for pulling the bar outwardly to disconnect it from the sash.

3. In awlndow structure, the combination with a frame, a plurality of sashes pivotally and slidably mounted therein, a window stop formed with a groove on its inner face, a traveling bar vertically movable in said groove, a clip through which the bar is slidable, said bar being detachably connected with one of the sashes, a stem on the clip extending through the stop and a lever on the stem for engagement with the stop to exert an outward pull 011 the bar whfireby to disconnect the latter from the sas 4. In a window structure, the combination with a frame of a plurality of sashes pivotally and slidably mounted therein, a window stop formed with a groove therein, a bar connected with the said sashes and vertically movable in the groove, a clip through which the bar is slidablc and a stem on the clip extending through an opening in the stop whereby the bar may be drawn into frictional contact with the stop for the purpose of affording a braking action to maintain the sashes in adjusted position.
